^PROJECT SHARE: TRIAL OF SCHOOL-BASED SEXUAL HEALTH PROGRAMME IN SCOTLAND^

Project SHARE was a cluster randomised trial carried out to measure the impact 
of a school-based sexual health programme in Scotland. A total of 25 secondary 
schools were randomly allocated to the intervention or control arms. A cohort
of 8430 students were recruited to the trial and 5854 were successfully 
followed up after two years. A wide range of outcomes were examined, but this 
dataset focuses on knowledge of sexual health, onset of sexual activity during 
follow-up and regret of sexual experience. Parental social class corresponds 
to the Registrar General's classification based on occupation (I is highest), 
based on highest social class of mother or father.
